I have a group at work that sends emails from a departmental account, that all of them have delegate access to. Occasionally (I'm not sure of the regularity), an email that was sent from someone accessing the departmental account via delegate access, will appear to be sent from the department account directly.

That is - often in the Gmail UI, it will look like this:

<department@gmail.com> (sent by user@gmail.com)

But another email sent by the same user not 1 minute later, looks like this:

<department@gmail.com>

I've not experienced this myself, but I don't doubt the users are accessing the departmental account via delegated access. Has anyone else experienced this?

Edit I just earned the Tumbleweed badge for this question, so I'm hoping I've waited long enough to bump this.
